Description

Fig cutting seedling method

Technical Field

The invention relates to the field of plant cutting propagation, in particular to a fig cutting seedling method.

Background

Fig (with the scientific name: Ficus carica Linn.) belongs to Moraceae, belongs to Ficus deciduous shrub, and belongs to subtropical deciduous small arbor. Also named as Tianxian fruit, Mingmuo, Yingri fruit, etc. There are known several hundreds of varieties of Ficus carica, most of them are evergreen, and only those longer than temperate zone are fallen leaves. The fruit is bulbous, the tail has a small hole, and pollen is spread by wasp. The fig trees mainly grow in tropical and temperate areas, the fig grows strongly and has multiple growth habits, and the annual growth of young tree young shoots and bare-grown branches can reach more than 2 m; the sprouting ability and the branching ability are weak, the growth of the bone trunk branches is obvious, the number of the latent buds on the bone trunk branches is large, the service life is long, and the service life can reach decades. The fig has the advantages of drought tolerance, shade tolerance, salt and alkali tolerance, fast growth, early fruit and high yield. The fruit is in the shape of a bulbous bulb, the fruit is in the shape of a flat circle, a sphere, a pear or a jar, the tail part is provided with a small hole, and pollen is spread by wasps. The color of the pericarp is also divided into green, yellow, red and purple-red, but most of the pericarp is yellow. The flesh is mostly yellow, light red or deep red.

The common fig seedling raising method is grafting seedling raising, but the grafting method is long in period and low in efficiency. The prior art also adopts a cutting seedling raising method, which comprises hardwood cutting and twig cutting, and because branches of more than 2 years are selected for cutting slips of the hardwood cutting, the cutting slips are completely lignified, the cutting rooting effect is poor, and the survival rate is low; and the cutting slips for the twig cutting usually adopt semi-lignified branches, so that the rooting is easier and the survival rate is higher.

Disclosure of Invention

The invention aims to provide a fig cutting seedling method which is simple in steps, convenient to manage, short in period, high in survival rate and capable of cultivating a large number of seedlings in a short time.

The technical scheme of the fig cutting seedling method comprises the following steps:

A. selecting cutting slips: selecting semi-lignified young shoot branches of current-year figs for 3-4 months, cutting the branches to be 15-20 cm long, reserving 3-4 buds, reserving blades at the top ends of the cutting slips, and cutting the lower portions of the cutting slips into inclined planes or double-inclined-plane wedges for moisturizing and storing;

B. cutting preparation: trimming and paving the seedbed matrix for 5-6 months, extruding a groove along the length direction of the seedbed, and inserting small holes with the same thickness as the cutting slips into the groove at equal intervals, wherein the depth of the holes is 10-15 cm; putting the lower part of the cutting into a growth regulator, soaking for 2-4 h, taking out and drying in the air;

C. cuttage: inserting the cutting into the small hole, burying until the upper part of the cutting is slightly higher than the plane of the seedbed, washing the cutting with water, simultaneously completely irrigating the matrix around the cutting, and dripping a growth regulator around the cutting;

D. and (3) performing cuttage post-treatment: building a shading shed to shade the cutting slips, and watering regularly; and observing survival conditions after 20-30 days of cuttage.

The matrix component in the step B is a mixture of humus soil, sandy soil, fine river sand and turfy soil, and the weight ratio is 1: 2: 3: 1.

the growth regulator in the step B and the step C is indoleacetic acid with the concentration of 1000-2000 mg/L or naphthylacetic acid with the concentration of 2000-2500 m/L.

And B, the distance between the grooves in the step B is 10-15 cm.

And D, watering at regular intervals in the step D for 3-5D, and completely watering the matrix around the cutting slips.

And step D, intermittently spraying water mist on the cuttings, and keeping the humidity in the shading shed to be 80-100%.

And D, heating the seedbed, and keeping the temperature of the seedbed matrix at 15-20 ℃.

The invention adopts semi-lignified twigs as the cuttings, and compared with hard twigs, the rooting rate is improved; the lower end of the cutting is soaked by a growth regulator before cuttage, and after the cutting is planted in a seedbed, the growth regulator is dripped into the matrix around the cutting, the effect and influence of the growth regulator on the lower end of the cutting are achieved twice, and the activity and rooting rate of the cutting can be greatly enhanced; the cutting shoots are sprayed with water mist intermittently, so that the humidity in the shading shed can be effectively kept, and the cutting shoots are promoted to take root; the seedbed is heated, so that the influence of the temperature difference change between day and night on the cutting can be prevented, and the normal rooting environment of the cutting is ensured.

In conclusion, the cutting method has the advantages of simple steps, convenient management, short period and high survival rate, and can cultivate a large amount of seedlings in a short time.
